RailWorks expanded CPR's track infrastructure at four sites in Northwestern North Dakota. The Class I railroad needed additional track capacity to suppport material deliveries and outbound oil production related to the construction and service of drilling rigs and pipelines to handle the oil boom and development of the Bakken shale oil fields.

CSXT expanded capacity on its strategic Chicago-Florida rail corridor and other sites identified for capacity improvements. RailWorks served as the prime contractor to self-perform the track construction work while managing subcontractors to perform the civil, electrical and drainage work.
